Comments: I bought these socks and my slap shot immediately improved, just kidding. These are cotton socks that attach easily to the velcro on your jock. The cotton is more breathable than the newer RBK Edge socks, which are polyester and trap more heat. You can also loosen the elastic on the bottom if you like to pull your socks over your shin guards. They will stretch over time to become longer, and they can be shrunk in the dryer to tighten up the fit. Overall more comfortable and more adaptable than polyester RBK Edge socks.From: Peter, CO
